This role is focused on maximizing the application of CAREL’s control and cooling solutions in commercial HVAC environments by developing, communicating, and implementing market best practices for medium-to-large equipment installations with OEMs and end-users. The Application Specialist guides OEM applications and commissioning for commercial HVAC equipment including Dedicated Outdoor Air Systems (DOAS), rooftop units (RTUs), commercial heat pumps, variable refrigerant flow (VRF) systems, and air handling units (AHUs), leveraging CAREL’s full portfolio of controllers, drives, dampers, heat exchanger, valves, and supervisory solutions.
This position provides comprehensive technical support for OEM pre-commercial initiatives, field installations, and system integration in commercial building applications. The specialist represents CAREL by providing strong technical leadership and supports regional strategy initiatives and projects. Reports to the Sr. Application Manager and works in close collaboration with the Global Marketing Solutions teams.
Role Overview
The Application Specialist proactively leads initiatives to apply efficient and advantageous CAREL control strategies for commercial HVAC systems. Reactively supports OEMs and building owners in early implementation phases, ensuring configuration and technical problems are addressed accurately and quickly. Serves as the CAREL commercial HVAC control expert and delivers technical training internally and externally.
Key equipment platforms include:
- Dedicated Outdoor Air Systems (DOAS) – energy recovery ventilators, dehumidification units, and fresh air handling for commercial and institutional buildings
- Commercial Rooftop Units (RTUs) – packaged and split rooftop systems serving retail, office, and industrial light-commercial facilities
- Commercial Heat Pumps – air-to-water, water-to-water, and geothermal heat pump systems including VRF controls for multi-zone commercial applications
- Air Handling Units (AHUs) and Fan Coil Units (FCUs) – terminal and central station air handlers for commercial, healthcare, and hospitality environments
- Chillers and Chilled Water Systems – commercial chilled water plant controls, primary-secondary pumping, and sequencing
Essential Duties and Responsibilities
Other duties may be assigned.
- Actively supports design and implementation of complete CAREL HVAC control solutions with OEMs in commercial markets, focusing on energy efficiency, dehumidification performance, ventilation compliance (ASHRAE 62.1), demand-controlled ventilation, and integration with BMS/BAS platforms.
- Guides OEM selection and configuration of CAREL controllerselectronic expansion valves, variable speed drives (CAREL inverters), and supervisory systems for DOAS, RTU, heat pump, and AHU applications.
- Supports commissioning, startup, and troubleshooting of commercial CAREL-controlled equipment at OEM facilities and customer job sites, with focus on refrigerant circuit optimization, economizer logic, heat recovery wheel controls, and humidity management.
- Provides technical expertise on integration of CAREL systems with building automation systems (BAS/BMS) via BACnet, Modbus, and LonWorks protocols in commercial building environments.
- Participates in product strategy and development discussions with CAREL’s global engineering teams based on commercial application needs
- Develops and delivers technical training programs, application notes, configuration guides, and commissioning documentation for OEM partners, mechanical engineers, and building contractors.
- Partners proactively with OEM engineering teams to help plan, design, and solve systemic control issues before units ship to commercial job sites.
- Collaborates with sales, engineering, marketing, and product management to develop commercial application solutions responsive to market needs.
- Communicates in a timely manner the status and actions needed for problem resolution internally and externally; elevates urgent issues related to commercial HVAC control failures or opportunities.
- Identifies best CAREL controller practices from the OEM and contractor perspective, developing application standards that address common commercial HVAC requirements.
Technical Focus Areas
Dedicated Outdoor Air Systems (DOAS)
The specialist will apply CAREL control solutions to DOAS equipment requiring precise outdoor air conditioning, energy recovery, and dehumidification. This includes control of refrigerant-based cooling and heating coils, energy recovery wheels, heat pipes, and runaround coils. Key competencies include demand-controlled ventilation (DCV) logic, ASHRAE 62.1 compliance, CO -based reset strategies, and integration of CAREL humidity sensors and controllers to maintain neutral or slightly positive supply air dewpoint. The specialist will configure and optimize CAREL controls for refrigerant circuit management
Commercial Rooftop Units (RTUs)
Expertise is required in configuring CAREL controllers and drives for packaged commercial rooftop equipment ranging from small tonnage split systems to large built-up rooftop platforms. The specialist will work with OEM engineering teams on compressor staging and variable speed control using CAREL inverters, economizer damper control sequences, heat exchanger management, and refrigerant circuit protection. Focus areas include demand response integration, power metering, and configuration of CAREL supervisory tools for fleet monitoring of multi-site RTU installations across retail and commercial portfolios.
Commercial Heat Pumps – Air-to-Water, Water-to-Water, and VRF
The specialist will support OEMs developing commercial heat pump products using CAREL controls. This encompasses reversing cycle management, defrost logic, refrigerant charge optimization with CAREL electronic expansion valves (ExV), COP monitoring, and integration with hydronic distribution systems Geothermal and ground-source heat pump controls, including ground loop management and fluid temperature optimization, are also within scope.
Air Handling Units, Fan Coil Units, and Central Station Equipment
Application of CAREL’s platform to commercial AHUs and central station equipment, including variable air volume (VAV) controls, static pressure reset, supply air temperature reset, heat recovery, and humidification using CAREL humidifiers. The specialist will guide OEMs in applying CAREL’s full controls ecosystem-sensors, valves, drives, and supervisory-within large commercial air handling platforms for healthcare, hospitality, and institutional applications.
CAREL Product Integration and Supervisory Systems
Deep working knowledge of the CAREL product ecosystem is central to this role, including controllers, CAREL electronic expansion valves, supervisory software, and CAREL variable speed drives (inverters) for compressors and fans. The specialist will guide OEMs and end-users in building integrated commercial HVAC solutions using these tools, ensuring correct configuration, programming, and commissioning.
Energy Efficiency and Building Integration
Commercial applications require a strong focus on energy performance. The specialist will apply knowledge of ASHRAE 90.1 requirements, ENERGY STAR certification criteria for commercial HVAC, demand response programs, and time-of-use energy optimization. Integration of CAREL supervisory platforms with building management systems via open protocols (BACnet IP, BACnet MSTP, Modbus RTU/TCP) and cloud-based energy monitoring solutions is a key responsibility.
